Vernon's-WHEEL.

Specification of Letters Patent.

Patented Feb. 1 1,1908.

Application filed November 19. 1906. Serial No. 344.050.

Another ob ect is to provide a' vehicle wheel thatxwill combine the durability and good tracti've properties ofv 'a solid tire with the resiliency of a pneumatic, while effectually protecting the latter from injury or other strains of travel.

A further object 1s to provide awh'eel in i which the resilient means are entirely incased, thereby preventing accidental 'displacement or inilury thereto.

I accomplish t ese objects by means of the device described herein and illustrated in the accompanying drawings, in which;

Figure 1. is a side elevation of my improved wheel. Fig. 2.. is an enlarged transverse section'taken on line 2-2 of Fi 1. Fig. 3.- is anenlarged sectional detail taken on line 3 3 of Fig. 2. Fig. 4. is an inner face view of the plate carrying the recess enga ing pins. Fig. 5.- is a perspecair of supporting s rings.

its-illustrated; in the drawings, tie wheel is composed of two members, an inner or hub carrying member 5, and an outer or spoke carrying member 6. The inner member 5 comprises a hub 7 having a bushing 8 held in place therein by keys 9. Secured to hub 7 by keys 9 are a plurality of annular guide lates,,10 and outside face plates 11, which ave a plurality of annular recesses or depressions 12.- Rigidly secured at their lower ends to the hub 7 in a suitable mannerare a series of springs 13 arranged in pairs, their tops terminating in a hinge joint 14, through which passes a bolt 15. This boltis ada ted to pass through annular inwardly exten ing members 16 and 17, being in screw threaded enga emcnt with member 17. Members 16 an( 17 are rigidly secured to an annular track or inner felly 18. Inner memher 5 is adapted to rotate on the axle 19 of the vehicle (not shown), and a screw threaded cap 20 prevents it from becoming disengaged therefrom. I

The outer or spoke member 6 is composed of a seriesof annular plates, 30 and 30 arranged in pairs so as to form annular-grooves 3-1, which are adapted to be engaged by the annular plates'10 secured to the hub-member 5. The outer edge of these annular plates 30 are preferably provided with annular angular grooves 32 and tongues 33 adapted to fit one within another and form a rigid construction, an annular metallic plate or cap 34 covering the peripheries of the plates through which are adapted to extend trans-- versely bolts 35.-

Centrally disposed between the plates 30 is an annular rigid track member 36, on the inner periphery of which are a plurality of' annular grooves 37, which are ada ted to form race wa s for balls 38, of a ball earing formed by t e inner felly 18 andrim 36. Spokes 39 are secured by bolts 40-to the up er annular rims 41 of the cap 34-.

' he outer faces of plates 30 are provided with a series of pins or rollers 42, which are adapted to enterthe annular recesses or deressions 12, thus allowing sufiicient play:

'etween the members 5 and 6 and at the same time holding them in engagement with one another'and preventing any accidental displacement. S okes 39 are secured to the inner'periphery o felly 43 of the outer member, w ich is provided with an annular recess or seat 44 in which is adapted to rest a solid elastic tire 45.

In operation as the outer member'fi of the wheel rotates the pins 42 secured to the plates 30 engage the sides of the recesses 12 ormedin the plates 11., and carry the inner or hub member 5 with it. If the vehicle should be passing over a rough road the shock to the outer member 6 1s communi cated to the springs of the inner member 5, thus relieving the vehicle of all jar and vibration, the recesses 12 being circular permitting a sufiicient upward play of the outer member without its becoming disengaged.

If desired a pneumatic tire could be sub-' I thereto, and an outer member comprising two annular rigid members connected together by spokes, and having a plurality of plates secured thereto so as to form annular grooves, said grooves adapted to engage the guide plates of the hub member, whereby the two members are held in engagement.

2. An interacting vehicle wheel, comprising a hub member having a resiliently supported telly and annular guide plates secured thereto, the inner faces of'the outer guide plates having circular recesses formed therein an outer member comprising two annular rigid swap-13 members connected together by spokes, and having a plurality of plates secured thereto so as to form annular grooves, said grooves adapted to e'rigage the guide plates of the hub member; and a plurality of engaging pins secured to-the outer faces of the plates secured to the outer member adapted to enage the circular recesses formed on the inner aces of'the outer guide lates secured to the hub member, whereby t e two members are heldlin engagement.

In Witness that I claim the foregoing 1- have hereunto subscribed my name this 14th day of. November, 1906 p NATHANIEL DRYD ENJ Witnesses:
